This snippet is a good example of Global Error Handling mechanism of UiPath. Almost every automation project handles exceptions in their own way. This exception handling can be enhanced even further by introducing Global Error Handling. This snippet is simply a plug and play workflow solution for global error handling. Just add this to your automation solution and you are ready to go!

What Global Error Handling does is, it will be the second level of error handling of any unmanaged or unexpected errors that occur while executing the workflow solutions. The global error handling xaml file will be called in such instances and it will try to retry the execution of the failed activity. The number of retry attempts are defined in the global error handler itself. If the retry attempts are successful, the workflow will continue to execute without any problem. However, if all retry attempts fail, the global error handler will terminate the execution of the process.

This snippet accepts two input arguments. Please make sure not to edit / remove these arguments as they are system defined and it will not work if you remove them. While executing these arguments will be used by the system in case of an unmanaged error. You do not need to pass anything or define invoke workflow activities to execute the global error handler.

Every retry attempt is logged in detail along with the exception information.

Project Configuration to support Global Error Handling

Please add the below line to your Project.JSON file under RuntimeOptions to enable global error handling:

exceptionHandlerWorkflow: GlobalHandlerForExceptions.xaml,

<p>Lahiru, would I use this instead of the Try Catch for the main activities?   And then only use a Try Catch for any activities I want to add in my Finally section?</p><p>MaryB</p>

Till now i can't recognize the benfit of global exception 

I tried many  excersize but did not see any change for the project before and after global exception handler

Clean and concise - Really good for what it does. Annotated and commented such that it is easy to understand, and comes ready out of the box to use in my workflows!


Great job :)


 - Have used this only a few times at this point and it seems to be quite useful
